记录一些hexo部署操作
- hexo版本: 6.3.0
- next版本: 7.8.0
下面部署步骤基于以上版本
长代码折叠功能
由 jQuery 选择器选择代码模块.highlight相关的DOM节点,给超过某个高度的代码模块添加展开收起的盒子,让盒子实现展开隐藏效果。
操作步骤:
添加
code-unfold.js由于是在
next主题中添加js逻辑,所以我们新建code-unfold.js放置在了themes/next/source/js/code-unfold.js`:1

jquery由于需要在
next主题文件中使用jquery不知道新版hexo在哪里才能引用
jquery.min.js,所以干脆自己下载到自己的项目,放到第1步创建的code-unfold.js边上一起引用。引用
jquery.min.js和code-unfold.js修改文件
themes/next/layout/_scripts/index.swig,最后添加两行:1
2{{- next_js('jquery.min.js') }}
{{- next_js('code-unfold.js') }}下面找到文件
themes/next/source/js/next-boot.js:添加一行代码:1

highlight.styl修改
themes/next/source/css/_common/components/third-party/third-party.styl文件,最后添加1
@import 'highlight';
styl文件的引入关系为:
themes/next/source/css/_common/components/components.styl引入
themes/next/source/css/_common/components/third-party/third-party.styl引入
theme/next/source/css/_common/components/highlight.styl
至此,我们就完成了hexo博客长代码折叠功能
